Norgren 61B2/BM000 Miniature Pop Type Valve - 1.6 bar Inlet
Part Number: 61B2/BM000
Quick Summary
Norgren 61B2/BM000 is a miniature pop type relief valve protecting compressed air systems. Operators deal with over-pressurization that causes downtime and wear; this device provides a reliable relief point. The brass body, pre-set relief, and tamper resistance support safe operation across -20 to 80 °C and 1.6 bar inlet. Ideal for direct connection to pressure vessels via R1/4 ports in compact air lines. In practice, it reduces maintenance, lowers safety risk, and stabilizes performance for OEMs and maintenance teams. Its compact dimensions—20 by 20 by 40 millimeters—and light weight help integrate into existing panels without redesign. Datasheets and CAD models are available to accelerate installation.

Feature → Business Impact → Application: The 61B2/BM000 features a pre-set relief mechanism that eliminates field adjustment errors, delivering consistent protection and reducing risk of unexpected venting. This translates to fewer unplanned shutdowns and safer startup sequences in manufacturing lines. Application-wise, it suits direct connections to pressure vessels through a standard R1/4 port, making retrofits and new builds straightforward in compact air systems. Feature → Business Impact → Application: The brass body provides corrosion resistance and mechanical robustness, extending valve life in harsh plant environments. This reduces replacement costs and maintenance downtime, particularly in OEM equipment and service fleets that handle continuous duty air systems. Use it in automation cells and packaging lines where reliability matters most. Feature → Business Impact → Application: The operating range of -20 to 80 °C accommodates diverse plant climates, ensuring stable performance from cold starts to hot operations. This minimizes temperature-related failures and variability in pressure relief behavior, supporting compliance with process control standards in automotive, food & beverage, and general manufacturing settings. Feature → Business Impact → Application: The compact footprint (20×20×40 mm) and light weight simplify installation in crowded control panels and on small vessels. This enables faster commissioning, reduces enclosure size requirements, and aligns with CAD-friendly workflows for quick integration with existing Norgren components. Feature → Business Impact → Application: A flowing capacity of 4.92 dm3/sec at up to 1.6 bar ensures adequate relief without excessive pressure drop, preserving system efficiency and protecting downstream components. Compatible with standard piping and assemblies, it supports scalable protection as lines expand or reconfigure. Feature → Business Impact → Application: The unit’s tamper resistance and ingress protection design address reliability concerns in maintenance-heavy environments, helping teams meet downtime targets and maintain consistent process performance across shifts. Compatibility with CAD models further reduces engineering time during design validation and installation.
